It mostly contains hydrators like honey and caffeine to help reduce inflammation. It's not a serum, but more like a moisturizer.

After 4-5 months of using the product - I have to say it does feel very nice on my skin and smooths on easily, but I haven't noticed much reduction in the puffiness.

That's not to say you won't see a difference. Give it a few months and take before and after pictures if you can - then compare for yourself.

My puffy eye situation is different. I had an eye injury when I was a little and that injury left my right eye puffy. It really became noticeable when I turned 40 something. I had laser surgery to remove some of the fat, but it still gets puffy easily when I'm tired, have allergies or a cold.
